B to light meson transition form factors calculated in perturbative QCD approach

Abstract

We calculate the $B\to P$, $B\to V$ (P: light pseudoscalar meson, V light vector meson) form factors in the large-recoil limit in perturbative QCD approach, including both the vector (axial vector) and tensor operators. In general there are two leading components ${\varphi }_B$ and ${\bar{\varphi }}_B$ for $B$ meson wave functions. We consider both contributions of them. Sudakov effects ($k_{\perp }$ and threshold resummation) are included to regulate the soft end-point singularity. By choosing the hard scale as the maximum virtualities of internal particles in the hard $b$-quark decay amplitudes, Sudakov factors can effectively suppress the long-distance soft contribution. Hard contribution can be dominant in these approaches.
